Singlespeed & Fixed Gear"I still feel that variable gears are only for people over forty-five.
Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Hmmm, good condition for a 30 some year old bike doesn't sound so "good".
New tires are not cheap if you get a decent pair.
Depends on what you want to do with it. Do you have a picture of it? It could be a project for you if you have the time.
I would pass on it and spend $100 on a CL bike that you can ride now.

Just bought it, and it is in better condition than he described over the phone. Only thing I really need to do is convert it to fixie, get cages and wait for a good deal on tires (tires are ridable). Maybe get a new BB, crank, pedals, seat and paintjob.

Overall, I am happy with this purchase, everything, especially the frame is in great condition.

I have one just like it. It's a pain in the **s to replace the front wheel. Stock axle is 5/16th so you'll have to do some filing to get a 9-mm axle in there. The front fork spacing is narrow too, 90mm ish. If it is Belgium built the bottom bracket should be 68mm english but the fork is almost certainly 26tpi Raleigh. So new fork = new headset.

the majority of raleigh grand prix bikes have proprietary 26 tpi bbs,and will be incompatible with everything but certain phil wood bb cartridges. funky bb shell and spindle widths and headsets too. that said i just finished converting a raleigh super grand prix into a single speed, and i like it a hell of a lot. you can and should spend a good bit of money overhauling it if you want to like riding it, but you can also do it without killing yourself. I did have a lot of spare parts I swapped out, but i could have gotten away with most of the original components, or gradually upgraded. upfront, i spent 100 on the bike and 120 rebuilding the rear wheel and replacing the rear tire. 220 aint bad for a good fitting,classy tank of a bike. Hi-ten for life.
